ISO calibration certificate for belt tension measuring device
System description
The PCE-BTM 2000A is a mobile test instrument for determining belt tension and trim forces in Belts, toothed belts, ribbed belts, drive belts and conveyor belts. An ideal belt tension is required to optimise the service life and the working process of the belt. With the PCE-BTM 2000A, you can record these values and compare them to the set point value. Due to a flexible sensor neck, measurements can be carried out even in narrow, difficult to access machine rooms. The belt tension is displayed in Hertz (Hz), the belt span force can be displayed in Newton (N) or optionally in pound-force (lbf).

Getting started
Power supply
Three AA alkaline batteries are required for power supply. The battery
compartment is located on the back of the meter and is secured with two
screws. Loosen the screws, lift off the cover, insert the batteries as
indicated and close the battery compartment by tightening the screws. Before
replacing the batteries, turn off the instrument.
Preparation
Before switching on the instrument, insert the sensor head into the sensor
socket of the meter and fix the head by tightening the knurled nut. To start
the instrument, press the On/Off key until the instrument name appears on the
display. To switch off the meter, press the On/Off key until the display turns
off. When the unit is switched on, the measuring mode icon appears on the
display together with a hand icon. Before first use and after each battery
change, you should set the date and time (see 5.2.2). To enter measuring mode,
press the Measuring mode key . If you would like to make settings, press the
Menu key to enter the menu.
Menu
You can enter the menu of the meter by pressing the Menu key after starting
the meter. You can navigate through the menu with the arrow keys . With the OK
key , you can confirm your selection. With the Back key , you can navigate one
step back.
Force
In the sub menu ”Force“, you can enter the values required to measure the trim
force. You can also choose whether or not the trim force will be displayed in
measuring mode.
Settings
Units
In the sub menu “Units“, you can select either the international unit system
(SI) or the Anglo American unit system (US).
Date & Time
In this menu, you can set the date and time. In the “Format” tab you can also
select how you want the date to be shown on the display.
Sound
Both the key sound and the sound when a measured value is recorded can either
be activated or deactivated.
Brightness
In this tab, the display brightness can be adjusted between 10 and 100 %.
Language
You can select one of these languages: English, German, Spanish, French,
Italian or Dutch.
Auto Power Off
You can define an Auto Power Off time between one and five minutes. The Auto
Power Off function can also be deactivated.
Memory
Select a folder in the first tab. This selected storage folder is used for the
following measurements to save the measured values. When you navigate to the
item “View memory”, the contents of the currently selected folder will be
displayed.
When you select one of the readings with the OK key , further details about
the reading will be displayed. Within this detail view, you can navigate
through the folders with the Up and Down keys. The arrow keys Left and Right
can be used to navigate through the detail views of the individual readings
within a folder.
Use the “Single delete” item to delete individual measurements in the selected
folder. When you delete a measured value in the middle of the folder, the
measured values within the folder are renumbered so that no numbering gaps
occur in a folder. If you want to delete all files in a folder, select the
menu item “Delete folder” and confirm that you want to delete the entire
folder. Via the last menu item “Delete all data”, you can delete the measured
values in all folders. In total, 15 folders are available. 50 measured values
can be saved to each folder so that a total of 750 measured data can be saved.
Calibration
By navigating to the “Calibration” item in the menu, you can calibrate the
sensor with a zero-point calibration. To do so, place the meter on a flat
surface and place the sensor head over a flat, bright surface. Click on
“Calibration” and wait until the calibration is completed. Now you can use the
device for the next measurement.
Info
In the “Info“ menu, you can find some information about the firmware version
of your meter.
Measurement
Measuring mode interface
If you have opened the “Measurement Mode” user interface, the device
automatically starts a measurement when a vibrating object is detected.
Moving the meter may cause low-frequency human vibration which are then shown
on the display as a measurement. In the standard settings, the first value
displayed is the belt tension in Hertz (Hz). Below this value, the trum force
is displayed in Newton (N). The lower part of the display shows the set values
for the mass of the belt per meter (weight icon) and the trum length (belt
icon). These values must be set individually for each belt but are not
relevant if only the belt tension is to be determined.
Preparing a measurement
To be able to carry out a first measurement, you must first make some
settings. It is recommended to calibrate the instrument after each restart.
How to perform a calibration is described in chapter 5.4.
To be able to generate measurement data for the trum force, you must first
enter the technical data of the belt. To do so, select the “Force” tab from
the menu. First enter the mass of the belt in kilogram mes per metre (kg/m).
Then enter the trum length in metres (m). Always confirm your selection with
OK .
Making a measurement
If you are still in the menu of the instrument, press the Measuring mode key
twice. The meter has now entered the measuring interface and will start
measuring as soon as vibration is detected. To obtain ideal measuring results,
align the sensor head so that the two measuring diodes or the white sensor
strip are parallel to the belt. You will obtain the most accurate measurement
possible if the optionally available sensor with long goose neck and coiled
cable PCE-BTM 2000A SHL is placed above the belt by means of the tripod STAT
as this avoids human vibration. In addition, the measuring probe should be
placed in the middle of the load trum if possible (see figure). The distance
from probe to belt should be between 10 and 25 mm. Now make the belt vibrate,
e. g. with the optional mallet.
Saving a measurement
To save a measured value, press the OK key after recording a measurement. The
selected folder as well as the number of the reading will be displayed. This
information will remain in the display for 4 seconds. During this time, the
meter PCE-BTM 2000A does not record any new measurements. After this, you can
proceed with your series of measurements.
Attention!
Before each measurement, make absolutely sure that the main switch of the
system is off and secure it against being switched on again. Never carry out a
measurement on running systems or rotating belts.
Calculation of trum length, belt weight and trum force
**Trum length
** As a rule, the trum length can be measured directly on the belt. Measure the length described above (trum length) and enter it in the “Force” menu as the length. Sometimes it is not possible to measure this length – then you can determine the length using the following formula:
ltrum = Trum length
lbelt = Belt length
d1 = Diameter of belt pulley 1
d2 = Diameter of belt pulley 2
Belt weight
If the mass per metre of the belt is not given, you have the possibility to
determine it yourself. To do this, weigh the belt and divide the weight in
kilogram mes by the total length of the belt in metres.
m meter = Mass per belt metre
m belt = Mass of the belt
l belt = Total belt length
Trum force
With the specified mass per belt metre, the trum length and the measured
frequency in Hertz, the trum force can now be determined. It is calculated on
the basis of the following formula:
F trum = Trum force
m meter = Masse per belt metre
l trum = Trum length
f = Frequency in Hertz
The determined trum force can be compared with the specifications of the drive manufacturers and the belt tension can then be adjusted according to the set point.
